在iPhone模擬器啓動應用程序在一段時間後失敗

Question

您好，我在Windows 10上使用Xamarin與Visualstudio Community 2015作爲構建主機我使用帶有iPhone5的Mac OSX 10.11.5（El Capitan）iOS 10.1模擬器 我可以構建/啓動/調試我的應用程序而無需進行約30分鐘的問題，即VisualStudio的後 構建應用程序比上啓動應用程序在模擬器的輸出窗口顯示：

Launching 'myapp.iOS' on 'iPhone 5 iOS 10.1'... 
Launch failed. The app 'myapp.iOS' could not be launched on 'iPhone 5 iOS 10.1'. Error: The post for client vs10440Matze on topic xvs/idb/4.2.1.64/launch-app has been cancelled. Please check the logs for more details. 
The app has been terminated. 

在Ide.log在Windows機器上，我可以看到：

Xamarin.Messaging.Client.MessagingClient Warning: 0 : [2016-12-09 10:48:38.4481] The post for client vs10440Matze on topic xvs/idb/4.2.1.64 /launch-app has been cancelled

在MAC-buildhost我可以看到：

IDB.log：

也同時建立我可以在Build.log常常重複該消息請參閱：

的VisualStudio停止調試視圖比立即。重新啓動Visualstudio會有所幫助，直到它再次發生。

關於任何幫助，我將非常感激。

嘗試關閉並重新打開Visual Studio。這應該可以解決您的問題:)
